READ INSTRUCTIONS

• Thoroughly read and understand this manual before using.

• Save for future reference.

PINCH AND CRUSH HAZARD!

• The Eastwood Press Brake Attachment consists of moving components

that quickly generate extreme crushing force which can present a hand/ﬁn-

ger pinch hazard and cause potentially serious injuries. Avoid pinching hands

while handling. Keep ﬁngers and hands away from moving parts

when operating.

CUT HAZARD!

• Handling sharp metal can cause serious cuts. Wear thick, well-ﬁtting

work gloves to prevent cuts from handling sharp metal.

EYE INJURY HAZARD!

• Metal particles can be ejected from the metal surface when bending.

Sheet metal edges and corners are sharp and can injure eyes.

Always wear ANSI approved eye protection when operating this tool.

DANGER indicates a hazardous situation which, if not avoided, will result in death or serious injury.

WARNING indicates a hazardous situation which, if not avoided, could result in death or serious injury.

CAUTION used with the safety alert symbol, indicates a hazardous situation which, if not avoided,

could result in minor or moderate injury.

NOTICE is used to address practices not related to personal injury.

SAFETY INFORMATION

The following explanations are displayed in this manual, on the labeling, and on all other information

provided with this product:

4Eastwood Technical Assistance: 800.343.9353 >> techelp@eastwood.com

• Before beginning ANY work with this tool, it is absolutely necessary that it be

mounted in a properly sized 12 to 20 ton hydraulic press which is securely

bolted to a sturdy workbench or anchored to the ﬂoor or wall.

• Strenuous physical force may need to be applied to the Press Brake Attach-

ment during use. Failure to ensure proper footing can quickly result in a fall

which could inﬂict serious personal injury or property damage. Always work

in a clean, uncluttered environment.

• Be sure there is sufﬁcient working room around the tool to allow for safe

handling of various sizes of metal.

• Excessive resistance while operating could indicate a defect with the work-

piece material or broken or damaged Press Brake Attachment components.

To avoid injury, stop work immediately and inspect workpiece material for

nicks, dents, welds, excessive scale or remaining coatings. Clean or repair

as necessary or discard and begin with a new piece. Also inspect Press

Brake components and host hydraulic press for looseness or damage.

OPERATION

• Follow speciﬁc operating instructions supplied with the particular hydraulic press to be used.

• Measure and mark the desired bend line on the workpiece panel.

• Slide metal panel between the Dies lining up your pre-marked bend line with the sharp, beveled

edge of the Male Die.

• Center metal panel in Press Brake.

• Gently and slowly draw down the hydraulic ram of the hydraulic press to begin creating the

desired bend. NOTE: The use of an angle gauge or protractor (not included) is recommended.

• Depending on the particular alloy being bent, it may be necessary to push the dies slightly

beyond the desired ﬁnished angle to allow for “springback”. Some trial and error is suggested

with scrap material before making ﬁnal bends.

MAINTENANCE

• Keep all areas of the tool clean particularly those surfaces that contact sheetmetal workpieces.

Dirt and metal chips can cause uneven clamping and inaccurate bends.

• Store in a clean & dry environment when not in use. Coat all machined surfaces with a light

lubricant ﬁlm of oil or suitable protectant to prevent rust formation.
